General Description
PCL-Azide (PCL-Nā), also known as azide-functionalized poly(ε-caprolactone) or azido-PCL, is a biodegradable polyester containing a terminal azide (Nā) functional group.
Poly(ε-caprolactone) (PCL) is a hydrophobic, biodegradable aliphatic polyester widely used in biomaterials, polymeric nanoparticles, and drug delivery research. Introduction of a terminal azide provides a bioorthogonal reactive site for further modification of the PCL chain.
The terminal azide participates in copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) with terminal alkynes and strain-promoted azide-alkyne cycloaddition (SPAAC) with strained cyclooctynes such as DBCO and BCN.
PCL-Nā can therefore serve as a versatile building block for preparing functional polymers, polymer-drug conjugates, ligand-functionalized nanoparticles, fluorescent polymer conjugates, and amphiphilic block copolymers.
